Patent number: 11124598Abstract: A method is useful for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the degradation of TEMPOL in mixtures with branched urethane resins.Type: GrantFiled: July 2, 2018Date of Patent: September 21, 2021Assignee: Hilti AktiengesellschaftInventors: Jens Bunzen, Anna Sharmak, Robert Dölle, Astrid Buder, Thomas Bürgel, Beate Gnass, Philipp Wieland, Sascha Dierker

Patent number: 8053498Abstract: Pulverulent polycondensation products are described, consisting of a) 5 to 95% by weight of a polycondensation product based on an aromatic or heteroaromatic compound (A) having 5 to 10 C atoms or heteroatoms having at least one oxyethylene or oxypropylene radical and one aldehyde (C) selected from the group consisting of formaldehyde, glyoxylic acid and benzaldehyde or mixtures thereof, and b) 5 to 95% by weight of a finely divided mineral carrier material having a specific surface area of 0.5 to 500 m2/g (according to BET as specified in DIN 66 131). The pulverulent polycondensation products according to the invention are outstandingly suitable in construction material mixtures in an amount of from 0.1 to 5% by weight, based on the weight of the construction material. The pulverulent polycondensation products have a number of advantages here, such as, for example, excellent storage stability, good liquefying action at low dosage and industrially simple production.Type: GrantFiled: December 18, 2006Date of Patent: November 8, 2011Assignee: Construction Research & Technology GmbHInventors: Philipp Wieland, Alexander Kraus, Gerhard Albrecht, Harald Grassl, Kerstin Becher

Patent number: 7910640Abstract: Disclosed is a polycondensation product that is a reaction product of A) an aromatic or heteroaromatic compound containing 5 to 10 C atoms or heteroatoms and is provided with an average of 1 to 300 oxyethylene groups and/or oxypropylene groups per molecule which are linked to the aromatic or heteroaromatic compound via an O atom or N atoms, and B) an aromatic compound and C) an aldehyde selected among the group of formaldehyde, glyoxylic acid, and benzaldehyde or mixtures thereof. Surprisingly, the inventive polycondensation product causes very good liquefaction of hydraulic binding agents, eg. Cement, resulting in substantially improved liquefaction of the construction material at a lower dose while pourability can be maintained over a longer period of time as opposed to naphthalene sulfonates or melamine sulfonates.Type: GrantFiled: October 14, 2005Date of Patent: March 22, 2011Assignee: Construction Research & Technology GmbHInventors: Philipp Wieland, Alexander Kraus, Gerhard Albrecht, Kerstin Becher, Harald Grassl
